And more of them have a harder time switching into Mega Charizard Y and Mega Camerupt. In Mega Charizard Y case, water types also can never switch into it easily due to Solar Beam in sun. For Mega Camerupt, it has a supreme wallbreaking quality with Sheer Force, Electric immunity and only weak to 2 types (makes it easier to build around). Additionally, Fire + Ground STAB is extremely good unless against Latios and Latias, which Victini and Mega Charizard Y also cannot beat.
